John BurekThe Best Computer Mice for 2019Time to ditch that old PC mouse, or move beyond your laptop's touchpad? We've got some click-worthy advice on buying mice for work or play—plus reviews of all the latest models. Check out our faves.

Pointing the Way: How to Buy the Right Mouse

In its most basic form, a computer mouse is simple hardware—a sensor on the bottom, two buttons and a scroll wheel on top—that lets you interact with programs as though they were extensions of your own hand. But while a mouse is simple in concept, the market for them is a scattered mess of types, prices, and designs. You need to know a little about the landscape when you go shopping for a new model.

Over time, distinct classes of mice have evolved, each made for different computing situations. The most common of these is the mainstream desktop mouse, designed for use with a desktop or laptop PC at a desk or table. Aside from the inevitable right and left mouse buttons, the usual features are a clickable scroll wheel and, in some cases, additional thumb buttons that let you navigate forward and back in your Web browser.

Travel mice (or "mobile mice") offer many of these same features but come in a smaller size. They're designed to fit easily into the pocket of a backpack or laptop bag.

For this same reason, however, travel mice tend to be small for most hands—you can use them just fine for short stints, but they become uncomfortable over long periods due to the unnatural grip required. Generally speaking, travel mice are wireless and battery-powered, so you may want to bring along a spare set of AA or AAA batteries.

The Right Mouse for Gaming

Gaming mice amplify every element of the basic mouse concept to the extreme: more buttons, higher tracking resolutions, curvier curves.

Some gaming mice are general gaming models, while others are designed for specific game genres. In the latter case, depending upon the style of the game that the mouse is intended for (first-person shooter, real-time strategy game, MMO title), you may see a variety of specialized features.

What most gaming mice have in common, though, is a combination of high-performance parts—laser sensors, featherlight click buttons, gold-plated USB connectors—and customization features, such as programmable macro commands and on-the-fly resolution switching. Gaming mice also stand apart in that the better ones tend to feature vendor-supplied software for setting up these custom features and shortcuts, defined sometimes on a per-game basis via profiles. The software's quality and functionality can vary wildly from vendor to vendor; that's where our reviews come in. Certain utilities are easier to pick up than others.

For maximum comfort, some gaming mice let you customize the body of the mouse itself. Removable weights are common, letting you tweak the total heft of the mouse one way or the other. Some models take this even further, letting you shift the center of balance, or adjust the height and pitch of the palm rest. For non-gamers, these features are overkill; for dedicated gamers, they provide a competitive edge.

Finding the ideal gaming mouse for you comes down to knowing your preferred style of game, determining whether or not you will take advantage of any of a mouse's more complex functions (it's easy to overspend on a gaming mouse), and then tweaking your choice to your specific tastes. If that's exactly what you're after, check out our roundup of the top gaming mice, as well as our roundup of special mice for MMO games.

What's the Best Ergonomic Mouse?

Ergonomics-first designs put all of the typical mouse functions into a form factor that places your hand in a neutral position. Designed to reduce the stresses that can lead to carpal tunnel and repetitive strain injury, ergonomic mice may look unusual and take some getting used to, but they do alleviate some very real problems. Some have a vertical design; others may have one-off sculpts.

Whether you're looking at a specialized ergonomic mouse or ergonomics are simply a concern in a more ordinary one, pay attention to the size of your mouse. (Make sure that it's not too big or too small for your hand.) Weight is also a consideration. Some people prefer a heavier mouse that anchors the hand, while others, especially players of MOBA games, want something light that furnishes little resistance to flicking and clicking. As a rule of thumb, a heavier mouse requires more effort to move, and even though the difference may not seem like much, over time it can mount.

It's not just weight and size that are important. The sculpting of the mouse can also lead to unnecessary strain on (or conversely, extra support for) your hand and wrist. The most comfortable mice will fit the contour of your hand, rather than having a flat, shallow shape.Some mice have a thumb rest, providing a resting spot from which the finger can rise as needed to activate controls.

Not Just USB: Mouse Connectivity

The simplest way to hook up a mouse to your PC is through a wired USB connection. Computer mice are usually plug-and-play devices, with no additional software to install (with the exception of higher-end gaming mice), meaning that plugging in the cable is all the setup you'll need to deal with. Unlike wireless alternatives, a wired device will draw its power over USB, so there are no batteries to worry about. Wired connections are also preferable for serious gaming or esports use (no battery to conk out in the midst of a match), though some high-end wireless mice are indistinguishable, from a response-time perspective, from wired ones.

If you want more freedom and less cable clutter on your desk, however, it's hard to beat a wireless mouse. Instead of a wired connection, wireless mice transmit data to your PC through one of two primary means: an RF connection to a USB receiver, or via Bluetooth. Both have their pros and cons, but if you want to reduce the number of cables on your desk and gain the flexibility to use your mouse unhindered—or even from across the room—wireless is the way to go.

Most wireless mice connect to the host computer via the same 2.4GHz wireless frequency used by cordless phones and some Wi-Fi Internet bands. A dime-size USB dongle—small enough to plug in and forget about—provides the link to your PC. Know, however, that only in some isolated cases (such as with Logitech's Unifying-branded gear) can a single USB dongle provide connectivity to more than one device. That means that unless the vendor specifically notes otherwise, you can't use the same adapter for your wireless mouse and keyboard. You may need to devote two USB ports to separate mouse and keyboard USB dongles.

Bluetooth options, in contrast, don't monopolize a USB port, and the stable, easy-to-manage connections are ideal for use with mobile devices, such as ultraportables, tablet PCs, and 2-in-1s. In regular use, a Bluetooth connection gives you roughly 30 feet of wireless range, but a Bluetooth mouse may not match the battery life offered by devices with an RF-based USB dongle. New innovations, such as motion sensors tied to power and connection management, can improve the battery life versus older Bluetooth devices, which maintained an always-on link that drained battery relatively quickly. But you'll want to look at the vendors' estimated battery life on a charge (as well as whether the mouse uses an internal battery you recharge, or disposables).

Sensors and Sensitivity

Most of today's mice use one of two types of light-based motion sensor: optical/LED, or laser. Unlike mechanical tracking options of yore, light-based sensors have fewer issues with dust and dirt, and the absence of moving parts means fewer failures.

Optical sensors pair a glowing LED beam—often red, blue, or infrared—with a small photo sensor, tracking movement by repeatedly imaging the surface below the mouse, translating any movement of the mouse into cursor movement. (The frequency of this imaging is called the "polling rate," expressed as hertz, or hundreds of instances per second.) Because of the imaging sensor used, optical mice are a little less prone to problems caused by lifting the mouse when in use or by mousing on an uneven surface.

Laser mice operate in a similar way, but they use an infrared laser diode instead of an LED. This allows, in some cases, for greater potential sensitivity (measured in dots per inch, or dpi) and polling rates. The one drawback is that they can be finicky about the surfaces on which they are used. Premium gaming mice generally use laser sensors, and they tend to work better with opaque mouse-pad surfaces meant for mousing; LEDs can be more forgiving. But this is not an absolute, and frankly, if you're concerned at all about mousing precision, a basic mouse pad will solve all ails.

To offer the higher sensitivity of a laser sensor and the versatility of an optical mouse, a few isolated mice use both in tandem. Most gaming mice also offer sensitivity adjustment, letting you shift from a precision setting for tight cursor-control circumstances (such as lining up a sniper's shot) to a broader-sweep one for melee combat and run-and-gun situations. This may be via dedicated-purpose button, or you may be able to program one of the mouse's buttons or toggles to execute resolution/sensitivity changes on the fly.
